Place dry ingredients and herbs in a mixing bowl, stirring well. To that, add mushrooms and cheese, creating a small well. In a separate bowl, whisk eggs and water and pour into the well, stirring to fully incorporate batter.
Place pot over medium-high heat and add cooking oil. Once oil has reached 350° F, using a #100 ice cream scoop, lower mushroom batter. Resist the urge to over crowd the oil. Allow munchies to cook approximately 1-2 minutes. Using tongs or a kitchen spider, carefully remove and enjoy immediately.
